What we need to do is walk the list of memdescs and record if there is
conventional memory at 0.
exists = 0;
for each memdesc;
if memdesc->start == 0 then
exists = (memdesc->type == conventional memory);
You must walk all memdescs, as later ones override earlier ones.
It's sufficient to check start here as only the first fpage is needed, and 0
is the lowest possible address (memdesc don't wrap around -1 :)
Thanks,
Marcus
